Background: Delayed excretion of high-dose methotrexate (HD-MTX) in pediatric acute lymphoblastic leukemia (ALL) can result in significant morbidity. While methotrexate is primarily renally excreted, HD-MTX may overwhelm renal excretion and increase reliance on fecal elimination. This study evaluated the association between laxative use for constipation and delayed excretion of HD-MTX.

Methods: This multisite chart review included pediatric patients with ALL (2010-2020) who received HD-MTX (5 g/m2). Delayed excretion was defined as a serum MTX concentration greater than 0.4 µM at Hour 48. We identified use of laxative medications after each HD-MTX infusion, with receipt of two or more doses considered …

Faculty, Staff and Students Publications

Background: Cardiovascular dysfunction frequently accompanies aging and is often worsened by adverse lifestyle factors and genetic susceptibility. The apolipoprotein E (APOE) gene modulates susceptibility to cardiovascular disease, but how exercise and diet interact with APOE genotype remains insufficiently understood. We investigate the cardioprotective potential of exercise in humanized APOE-targeted replacement mice on control and high-fat diet, using photon-counting computed tomography (PCCT) and deep learning-based image segmentation.

Methods: This study included 251 male and female mice in mid-to-late life of APOE2, APOE3, and APOE4 genotypes with variation in humanized NOS2 (HN) mediated innate immune response, exercise status (exercised vs. sedentary) and …

Structural Dynamics And Binding Of Caenorhabditis Elegans Lifespan-Extending Lipid Binding Protein-3 To Polyunsaturated Fatty Acids, André R Cuevas, Matthew C Tillman, Meng C Wang, Eric A Ortlund

Faculty, Staff and Students Publications

Intracellular lipid binding proteins (iLBPs) play crucial roles in lipid transport and cellular metabolism across the animal kingdom. Recently, a fat‐to‐neuron axis was described in Caenorhabditis elegans, in which lysosomal activity in the fat liberates polyunsaturated fatty acids (PUFAs) that signal to neurons and extend lifespan with durable fecundity. In this study, we investigate the structure and binding mechanisms of a lifespan‐extending lipid chaperone, lipid binding protein‐3 (LBP‐3), which shuttles dihomo‐γ‐linolenic (DGLA) acid from intestinal fat to neurons. We present the first high‐resolution crystal structure of LBP‐3, which reveals a classic iLBP fold with an unexpected and unique homodimeric …

Averting Collapse: Reimagining The Ntds Ecosystem Through G20 Health Diplomacy And Science Innovation, Maple Goh, Peter J Hotez

Faculty, Staff and Students Publications

The recent termination of the U.S. Government's neglected topical diseases (NTD) mass treatment program, following similar cuts by the UK, threatens decades of progress. Without a strategic reset, NTDs may re-emerge, exacerbating poverty across Africa and beyond. We call for a broadened donor base and reframing NTD control as a shared global interest, especially as NTDs rise in G20 nations due to climate change and urbanization. This moment demands investment in sustainable tools, like NextGen vaccines and biologics, and greater leadership from G20 countries. While USAID's exit is a setback, opportunities arise for decolonizing global health and fostering new partnerships.

Faculty, Staff and Students Publications

Background: Chylomicronemia is characterized by fasting triglyceride (TG) ≥1000 mg/dL; its longitudinal course is not well studied.

Methods: Using National Health and Nutrition Examination Survey (NHANES) data (1999-2018; n = 21,998), we determined chylomicronemia prevalence and temporal trend. Using Mayo Clinic data (4,524,506 TG measurements for 1,294,044 individuals), we studied the longitudinal course and ascertained persistent chylomicronemia (PC), defined as TG ≥1000 mg/dL in more than half the measurements for individuals with ≥3 measurements. We used logistic regression to assess factors associated with PC.

Results: In NHANES, the prevalence of chylomicronemia was 0.20% overall, with higher prevalence in men (0.32%) …

Simulation Model To Estimate Pretreatment (Baseline) Low-Density Lipoprotein Cholesterol Levels In People Living With Homozygous Familial Hypercholesterolemia, Jing Gu, Robert J Sanchez, Alexandra Koumas, Sandeep Tripathi, Harshit Dixit, Adam Amer, Laurence Sperling, Christie M Ballantyne

Faculty, Staff and Students Publications

Introduction: Pretreatment levels of low-density lipoprotein cholesterol (LDL-C) are a primary consideration for the clinical diagnosis of homozygous familial hypercholesterolemia (HoFH). However, determination of pretreatment LDL-C can be challenging in this population because many individuals begin lipid-lowering therapy (LLT) early in life before diagnosis of HoFH.

Methods: A previously developed simulation model was adapted to estimate pretreatment LDL-C in people living with HoFH, based on their treated LDL-C value and current LLT (statin, ezetimibe, alirocumab, evolocumab, and/or lipoprotein apheresis).

Results: The tool includes an interface for users to provide relevant details for estimating non-clinical pretreatment LDL-C, specifically for patients suspected …

Stent thrombosis remains a major complication following percutaneous coronary intervention, with significant morbidity and mortality implications. Despite advancements in drug-eluting stents and optimized pharmacotherapy, real-world registry data indicate that definite or probable stent thrombosis occurs in approximately 0.5% of percutaneous coronary intervention cases, with a 30-day mortality rate approaching 25% and a long-term risk exceeding 30% at 10 years. Stent thrombosis is classified based on timing into acute, subacute, late, and very late thrombosis, with subacute and very late stent thrombosis being the most prevalent. Clinical consequences include myocardial infarction, emergent revascularization, and heightened cardiovascular risk, necessitating timely recognition and …

Testosterone Plus Lifestyle Therapy Improves Skeletal Muscle Glycolysis In Older Men With Obesity And Hypogonadism, Viola Viola, Marlene Aguilar, Maria Liza Duremdes Nava, Alessandra Celli, Reina Armamento-Villareal, Yoann Barnouin, Nicola Napoli, Nagireeddy Putluri, Clifford Qualls, Dennis T Villareal

Faculty, Staff and Students Publications

Objective: Weight loss in older men with obesity and hypogonadism accelerates musculoskeletal decline, yet the underlying metabolic mechanisms remain unclear. Testosterone replacement therapy (TRT), when added to lifestyle therapy (LT), mitigates this decline, but its metabolic basis has not been defined. We examined skeletal muscle metabolomic adaptations to LT with or without TRT, focusing on glycolysis, the pentose phosphate pathway (PPP), the tricarboxylic acid (TCA) cycle, and carnitine metabolism to identify dominant pathways of metabolic adaptation.

Design: Randomized, double-blind, placebo-controlled trial (LITROS).

Methods: Eighty-three men aged 65 years or older with obesity (BMI ≥30 kg/m2), hypogonadism (testosterone < 10.4 nmol/L), and frailty (Physical Performance Test score ≤31) were randomized to 26 weeks of LT plus TRT (LT+TRT) or LT plus placebo (LT+Pbo). A metabolomic substudy was performed in 44 participants, who underwent serial biopsies of the vastus lateralis for targeted LC-MS/MS analysis of intermediates in glycolysis, PPP, TCA cycle, and carnitine metabolism.

Results: Among the …

Exploring The Association Between Childhood Anxiety And Stressful Urban Life Events, Diya Cheema, Sydney Sumrall, Robin Everhart, Marcia Winter

UROP Posters

Objective: Research indicates that children who live in underserved urban environments are more likely to experience behavioral problems, such as social withdrawal, school adjustment problems, and self-reported delinquency (e.g., King, Huang, & Dewan, 2022). Studies have shown that for adolescents who later develop anxiety and depression, the neighborhood during childhood development could be a factor (Lee et al., 2018). Environmental conditions such as a higher risk of exposure to violence, limited community resources, and undergoing a significant life change in childhood can result in greater risk for psychological distress, including anxiety (King, Huang, & Dewan, 2022). The purpose of this …

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within …

Single-Cell Multiome Characterizing Intercellular Communication And Intracellular Regulation Of Epithelium And Mesenchymal During Secondary Palate Development In Mice, Usama Hussein, Yulin Dai, Andi Liu, Toshiyuki Itai, Fangfang Yan, Lukas M Simon, Zhongming Zhao

Faculty, Staff and Student Publications

Cell-cell communication between adjacent tissues is fundamental to orchestrating organ morphogenesis. During secondary palate development, interactions between epithelial and mesenchymal cells regulate epithelial-mesenchymal signaling, thereby controlling cell proliferation, differentiation, and tissue patterning. However, the precise molecular mechanisms underlying these interactions remain largely unexplored. In this study, we employed single-cell multiome sequencing to simultaneously profile chromatin accessibility and gene expression in 35,150 individual cells isolated from the developing mouse secondary palate at embryonic days E12.5, E13.5, E14.0, and E14.5. Our analysis revealed that intercellular signaling plays a pivotal role in directing secondary palate morphogenesis, with WNT, BMP, and PDGF pathways emerging …
